Abstract

High-purity samples of potassium trifluoroargentate(II), KAgF3, have been obtained via a novel synthetic pathway. This compound is found to exhibit an order–disorder phase transition around 230 K. Susceptibility measurements indicate that KAgF3 exhibits strong antiferromagnetic (AFM) coupling reminiscent of that found in copper(II) oxides.
